VGROUND-ANCHOR.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed November 19,1906. Serial No. 344,070-

companying drawings, in which similar reference characters indicate the same parts,

and wherein Figure 1 is a side elevation of a groundanchor constructed according to my invention and with its parts arranged to be driven into the ground. Fig. 2 is a longitudinal sectional view of the plate, "illustrating the parts in anchoring position. Fig. 3 is aplan view of the device as illustratedin Fi 2, and Fig. 4 is a plan view of the undersi e ofthe v anchor-plate.

The anchor-plate b 'is preferably formed with a central triangular point a at one end.

and a pair of triangular inclined points 41 at the sides of its 0 posite end, thus resenting a substantially art formation. groovef'e extends centrally and longitudinally of that side of the plate uppermost when embedded in the ground, and a rib f is similarly dis posed at the opposite side of the plate, such plate bein preferably of sheet. metal and the groove an -rib formed in one operation.

A pair of perforations gthrong with their centers intersecting the plate, re-

ceive a pin it, and the portions of theflanges (constituted by the plate) at opposite sides of the rib and contiguous to the perforations are raised, as'at 7c, toenable these perforations to be located in the plane of the point of the plate.

- A bar m is provided bywhich the anchorslotted, as at plate is-driven into the ground and which also serves as. a portion of the sta connecting the late to the thing to be anc ored or braced. his bar has one end portion preferably flattened, as at n, to fit into t e. groove and 0 to receive the pin, while the extremity of this end portionhas one side rounded, as at p, concentricallywith the adjacent end. of the slot and its other side squared to form a shoulder'g, while the op 0'- site end of the bar has an eye 1 or ot er means to enable a staywire or the like to be connected thereto.

reaches the pin, when the plate begins. to

When putting my improved ground-anchor in use, the plate is turned to lie against the bar, thus bringing the point 0 into alinement with the axismithe bar, and the latter is pushed toward the point of the dart, (such movement being accommodated by the slot 0,) in which posltion the plate is locked by the portion of the bar promoting beyond the connecting-pin. The entire device is then driven into the ground by means of a sledge,

after which the bar is drawn upon until checked by the anchor-plate. In this latter action the bar first slips along the groove in the plate until the lower end of'the slot move with it and the inclined pointsturn the dart gradually to a osition at right angles to the bar, the roun ed side 1) permitting of,

such movement and the square shoulderg checkingithe same when the plate assumes its proper ancho position. (See-Fig. 2.) It will'be noted t at the raised portions 7:

protrude very little and, being curved, ofier practically no resistance to the driving of the device or the movement of the plate as it assumes its anchoring ward endof the rib eing beveled offers no resistance either to the driving of, the device.

What I'claim is as follows: 1. A ground-anchor comprising an anchor- .ing member: and a bar-connected thereto, such bar being adapted to .serve the dual function of astay means whereby the anchoring member is driven, suchanchorin member extending'beneath the lower end '0 the said bar when in anchoring position. 2, A ground-anchor comprising an anchorlate and a bar connected thereto, such bar ing adaptedto serve the dual function of a position, while the forstay and meanswhereby the anchor-plate 5 is driven, such anchor-plate extending beneaththe lower end of t e said bar when in anchoring position. 7 I I 3. A ground-anchor comprising a metallic length and an anchor-plate connected thereto by a sliding pivotal connection and means IOO for preventing movement of t e plate inone direction past a predeternnne angular os tion. \p l l, 4. A ground-anchor com rising an anchorf plate and a bar connected t eretowith a slid- 1 pivotal connection such bar bemg adapte fto serve the dual function of a stay and means whereby the anchor-plate 1s driven.

5. A ground-anchor compnsmg an anchor;

plate having a-longitudinal groove below one surface thereof, and a rigid bar pivoted to the plate within the groove.

6. A ground-anchor comprising an anchorplate with a longitudinal groove in one side, a rigid bar slotted near one end, and a pin pivoting the bar to the plate with its slotted end within the groove.

7 A ground-anchor comprising an anchorplate with a longitudinal groove in one side and a longitudinal rib upon the other side, a rigid bar slotted near one end, and a pin pivoting the bar to the plate with its slotted end within the groove.

8. A ground-anchor'comprising an anchorplate, a rigid bar having one end partially rounded and formed with a square shoulder, and means pivoting the bar to the plate.

9. A ground-anchor comprising an anchorplate, a rigid bar having one end artially rounded and formed with a square s oulder, arlid slotted means pivoting the bar to the p ate.

10. A ground-anchor com rising an anchor-plate with a longitudina groove in one side and a longitudinal rib upon the other side, a rigid bar havin one end partially rounded and formed wit a square shoulder,

and a pin pivoting the bar with the said end Within the groove.

'11. A ground-anchor comprising a plate 1 with a longitudinal groove in one slde and a longitudinal rib upon the other side, a rigid bar having one end slotted and artially rounded and formed with a square s oulder, and a pin pivotin the bar to the plate with its slotted end wit in the groove.

12. A ground-anchor comprising a plate I) with points 0 and cl, groove 0, rib f, perforations gvand raised portions k; a rigid bar m having slot 0, rounded portion p and shoulder 9; and pin h, substantially as described and for the purpose set forth.

13. A sheet-metal anchor-plate for the purpose set forth having a longitudinal groove in one side with transverse perforations the centers whereof lie in axial alinement and in the plane of the side in which the groove is formed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
